What are the details about the music in the Ubuntu One Music Store?

Songs purchased through the Ubuntu One Music Store are available in high quality 256 kbps (sometimes higher) MP3 audio encoding and without digital rights management (DRM). MP3 purchases can be:

burned to a CD any number of times

played through any software on any type of computer that you own that supports MP3

synced to any MP3-enabled device such as a portable music player

You may occasionally find songs in WMA format. We're working with our partner to remove these songs from the Ubuntu One Music Store. Until this is resolved, we don't recommend purchasing these songs in this format. An MP3 version can typically be found by using the store's search feature. There will be no embedded 'watermarks' of any kind on the MP3s in the Ubuntu One Music Store.

Some have asked for songs in other formats such as Ogg Vorbis or FLAC. Acquiring popular songs in this format was not possible at this time, but Canonical will continue to look for future opportunities to improve the quality of the songs found in the Ubuntu One Music Store.
